Reynolds Advance Materials/Smooth-On. Can't recall exactly which product at the moment, it's written down in a file. I'm dubious on 3D prints holding up for this application but willing to be proven wrong. Depending on the layers and print orientation, some teeth will be stronger than others.@CruiserTrash What material did you use so I can avoid it?
My buddy's printer is getting an upgrade and will be back in a couple weeks, he said he would be happy to print one and see how it goes.
